Portable Generator Power Backup Solutions

I’m trying to put together a basic, low-cost power backup solution using a portable generator. My goal isn’t to build a fully automated or whole-house system — just something simple and safe that will let me power my refrigerator and a few lights during an outage without having extension cords running through open doors and windows.

What I’m thinking:

A portable generator

A way to feed a few circuits in my panel (fridge + lights)

Manual connection — I don’t need automatic transfer switches or deep integration

What I don’t want:

A fully automated or whole-house system

A complicated/expensive installation

Extension cords taped through doors

Questions for the group:

Any brand recommendations or specific products worth considering?

Recommendations for electricians?

Thanks in advance.
